This trial tests a combination of four drugs—two immunotherapies (QL1706), an anti-angiogenic agent (anlotinib), and chemotherapy (nab-paclitaxel)—as a first-line treatment for advanced triple-negative breast cancer. The goal is to see if this combination slows or stops cancer growth better than standard treatment alone.
Nanjing, JiangsuAges 18–75 - NCT07016399RecruitingPhase 2
Darolutamide before surgery for AR-positive triple-negative breast cancer
This trial tests a drug called darolutamide, alone or with standard chemotherapy, before surgery for a type of breast cancer that is triple-negative but has a high level of the androgen receptor (AR). It is for people with stage II or IIIA breast cancer that can be removed surgically.
Nashville, TennesseeAges 18 years+ - NCT07581834RecruitingPhase 2
Dalpiciclib plus hormone therapy for early hormone-positive breast cancer
This study tests whether adding a new drug called dalpiciclib to standard hormone therapy improves outcomes for women with early-stage breast cancer that is hormone-receptor positive. The goal is to see if this combination is more effective and safe than hormone therapy alone.
Fuzhou, FujianAges 18 years+ - NCT06365788RecruitingPhase 2
Bicalutamide and Abemaciclib for AR-positive Triple-negative Breast Cancer
This trial tests a combination of two oral drugs—bicalutamide and abemaciclib—for people with a specific type of advanced triple-negative breast cancer that grows in response to androgen hormones (AR-positive). The goal is to see if this treatment can shrink tumors or slow disease progression.
AntwerpAges 18 years+ - NCT05983107RecruitingPhase 2
Chidamide/Everolimus for advanced breast cancer
This trial tests a combination of two drugs, chidamide and everolimus, for people with advanced HR+/HER2- breast cancer. It aims to see if the combination works for tumors with or without a PIK3CA gene mutation. You may be able to join if you've had previous treatment with CDK4/6 inhibitors and up to two prior chemotherapies.
Beijing, Beijing MunicipalityAges 18–75 - NCT06605521Recruiting
Study on removing lymph nodes above the collarbone for breast cancer
This trial tests if removing cancerous lymph nodes above the collarbone helps treat breast cancer that has spread there. It aims to see if this surgery, along with standard treatments, is safe and effective.

Induction chemo then immunotherapy for PD-L1 positive triple negative breast cancer
This trial tests a two-step approach: first a short course of chemotherapy (paclitaxel and bevacizumab), followed by a combination of immunotherapy (atezolizumab) and a different chemotherapy (nab-paclitaxel). It's for people with advanced triple-negative breast cancer that has spread or cannot be removed, and whose tumors have a specific marker called PD-L1. The goal is to see if this sequence works better than standard treatments.
